I have charged a couple of cycles now. The battery indicator seems to be reasonably accurate but the guessometer is still a bit optimistic. It show 145 km range at full charge while reality is less than 100.

A final report. The guy who sold CMU boards on ebay had the right board for me. I have no garage so it was a bit problematic to change the board, but this weekend I could do it at work. It was easier than I thought to remove the battery and change the board. Now the car is running fine again...

Yes, I have dropouts on all the cells. One cell is more severe, but I can see fluctuation on all the cells (This pack has 4 cells). Today I found a guy from the Netherlands, who is selling these boards on ebay, and I ordered one. I am wating for his respond about the numbering. I think that he...

Thank you for the answers. I found a monitor function in Diagbox, and the cell voltages on CMU12 looked like this As the dropouts are completely random it looks like the IC that reads the cell voltage is failing. The IC is from Analog Devices and I just happened to have an account there, so...

Hi. This is my first post here. My I-miev from 2011 will not charge more than for about a minute or so. It started with interrupted charging now and then, but now it is almost impossible to charge. I get error P1A81 from the BMU, and the yellow light comes on. When I checked the voltages from...
